THOMAS E. DUGLE BY 1 2,711,299 ADJUSTABLE MOUNTING MEMBER Thomas E.Bugle, Cincinnati, Qhio, assignor to Pianet Products Corporation,Cincinnati, Ohio, a corporation of Ohio Application March 2, 1954,Serial No. 413,642 2 Claims. (El. 248-27) This invention relates to anadjustable mounting,

member, and particularly to an idler pulley mount.

An object of the invention is to provide simple yet highly effectivemeans for adjustably mounting an elongate element, such as a shaft, orthe like, whereby its axis may be shifted relative to a support element.

Heretofore considerable ditficultyhas been encountered in providingsuitable mounting means for elongate elements, such as shafts to whichidler pulleys are mounted, particularly in those instances where itbecomes desirable or necessary to tilt the axis of a shaft toaccommodate changes in the tracking conditions of an endless memberpassing over the idler pulley carried by the shaft.

The subject device enables an operator to quickly align the shaftrelative to a support element for disposing an idler pulley in desiredalignment'with the endless member passing thereover. Such adjustment maybe effected in all three planes, thereby greatly enhancing the overallutility and value of the mount.

Another object of the invention is-to provide an idler pulley mountwhich includes a housing, and means for adjustably securing the housingrelative to a support element; a spool rotatably received within thehousing, said spool including means for clamping a shaft thereto; andmeans for clamping" the spool relative to the housmg a mounting memberhaving the hereinabove described Still another object of the inventionis to provide.

7 i the spool for securelyv though releasably clamping thecharacteristics which is fabricated from a minimum number of parts whichco-operate whereby to securely though releasably position a shaft in anyone of a variety of positions relative to a supporting element. 7 Theseand other objects are attained by the means described herein and asdisclosed drawings, in which: Fig. 1 is a side view of an adjustablemount embodyin the accompanying ing the teachings of the presentinvention, with portions 7 of the clamping means cut away forclarity ofdetail and understanding.

Fig. 2 is a view taken on lines 2-2 of Fig. 1.

Fig. 3 is a front elevation of the device of Fig. 1 show/ ing, in dottedoutline, various positions which the pulley is capable of assuming.

Fig. 4 is a sectional view taken on line 4-4'of Fig. 3.

With particular reference now to the drawings, the numeral 10 denotesgenerally a housing which,in the preferred embodiment of the invention,is substantially cylindrical, the rear end thereof terminating in anannular flange or mounting lip 12.

The body portion of the housing, which extends forwardly from lipsloosely received in and extend forwardlyfthroughan opening 14 providedin a support element 16, for locating the forward face 18 of mountingrelationship with rear face Suitable means such as, by way of example, aclamp ring 22, may be employed for securely though releasably clampinghousing 10 relative to support element 16 by means of bolts 24, whichextend therethrough, and lip 26, which will be drawn against outer face28 of lip 12 when the bolts are tightened.

Housing 10 is provided with a first, through, axial bore 30, and with asecond bore 32 which intersects the first bore at right angles. As bestillustrated in Fig. 2, bore 32 extends diametrically through thehousing.

gate member such as, byway-of example, a shaft 44, upon thefree forwardend of which a pulley 46 may be rotatably mounted on bearings 48, noteFig. 1.,

Suitable means, such as set screws 50, are carried by spool onto shaft44..

As best illustrated in Figs. 2 and 4, shaft 44 extends. through thefirstibore 30 0f the housing, the diameter of said bore beingappreciably larger than the diameter of tothe axis of the spool.. slotand is provided for tive to the axis of the first bore 30. I

As best illustrated in Fig. 4, partial rotation of spool 40 results :inshaft 44 being tilted about the axis of the spool foretfecting'substantial angular adjustment of the shaft in a plane normalto the axis of the spool. I

It. will likewise be noted'that the entire axisfiof'the spool may beshifted relative to the support element 16 by shifting the housingitself relative .to said, element. From the foregoing it will be notedthat the adjustable mount permits an elongate member, such as; shaft 44,to be adjustably mounted in an infinite number of positions relative tofixed support elementi16. p p p As illustrated in Figs. 1 and 4, slot6ll extends'be- 'twe en front face 162 and the second bore32'of the,"
